Where does 10,000 steps a day come from?
Dr. Lee discovered that the origins of the number go back to 1965, when a Japanese company made a device named Manpo-kei, which translates to “10,000 steps meter.” “The name was a marketing tool,” she says. But since the figure has become so ingrained in our health consciousness (it’s often the default setting in fitness trackers), she wanted to see if it had any scientific basis for health.
